What the topic is- My topic is about how when light enters the eye it becomes inverted when it reaches the retina. If the light hits the retina inverted why don’t we see everything inverted? How it related to light and optics- The eye is related to light and optics because the eye takes light and it goes through a lens to focus light on the retina to produce and image. To understand how the eye inverts the image and focuses it on the retina we have to know how light acts when in hits a lens. How it works- Why do we not see all images upside down if the light reaches our eye inverted? The reason is because the brain changes it right side up for us. Your brain is so used to seeing things upside down that eventually it just adjust to it, this is done by the optic part of the brain. There was a study done where participant where given glasses that made them see everything upside down after a few days of wearing these, they began to see right-side up again even with the inverting glasses on. When they took the glasses of everything became upside down again because the brain had adjusted to the glasses. A few days later there vision returned to normal. It is believed that newborn babies see everything upside down for the first few days until their brain adjusts.
